Yeah that little Sporty powered Buell Didn't have much more after 120. I still have the kick start only '67 CH I bought new when I was in my 20s. I had to quit riding it after it was 86 Inches and I was in my 60s. I have the Buell ZTL2 Rim mounted Disk and 8 Piston Caliper mounted on my '08 K 12 S. Love the brake and it looks killer.
I'd guess the directional is a short if the socket looks OK. It should be showing a light fault on the dash, right?
As for the Power Commander and what ever the previous owner did; first off, you can put the file back to stock as a starting point. Go to their website to see how this is done. From there, you should make up your mind what you are going to do with your bike and make all those changes. Pipes, Muffler, Air Cleaners or any other intake mods. any engine modifications, etc. You'll want to have a well running set of injectors in place, run a couple doses of fuel system cleaner thru it at the very least . Put a new set of spark plugs in and then go spend the money on the Dyno tune. Also, Did you ask the owner what he has on the bike? When ever I buy a vehicle, I take notes.
As for the O2 sensor, It's not really attacked to the starter. It plugs into the main wire harness up in that area on the right side under the back of the gas tank. You may be able to see if it's unplugged by going in there with a small lite and a mirror. If you can't see it, you'd have to take the tank off to tell for sure.
Removing the tank is not that big a deal. You take the seat and the tank skins off. There is two large bolts in the back and the gas line is a quick disconnect that will not spill one single drop when removed or installed. there is an elec. connector and two other breather hoses in the same vicinity as the gas line and that's it. While you're in there, you can check all your hoses and wires for rubbing and blow the piles of dead bugs out with an air hose. %^D
